SEPARABLE BUTTON.

SPECIFICATION forming part of Letters'Patent No. 478,174, dated July 5,1892.

Application filed May 11, 1891- Serial No. 392,334; (No model.) A

will enable others skilled in the art to which it pertains to make anduse the same, reference being had to the accompanying drawings, whichform a part of this specification.

This invention relates to a separable linen button, and has for itsobject a button in which. the head and shank are made solidly togetherand the foot is made to receive the shank, protect it by means ofsuitable flanges from being turned or moved by the edges of thebuttonhole through which the shank passes, and is also made to receiveand hold securely a cross-bar on the shank and thus prevent the twoparts from being separated except at times when the one part is turnedwith respect to the other forcibly for the purpose of causing suchseparation.

In the drawings, Figure 1 shows the two parts of the button separated.Fig. 2 shows the foot-piece with the uprising flanges bent backward toshow the locking parts. Fig. 3 shows in section the two parts lockedtogether. Fig. 4 shows in section the two parts placed together inposition to be. turned, but not yet to be turned into lockingposition,,.

A represents the foot part of the button made of a strip of spring metalhaving the two ends bent inward and upward. The uprising portions of theends of the strip of metal do not quite meet, but leave a space betweenthem sufficient to allow the passage of the cross-bar I) attached to thefoot of the shank b ofthe bottom part B. Along the perpendicular middleline of the uprising part of the foot A the strip of metal is bent orcorrugated so that the two opposite bends present a tubular'form of asize sufficient to permit the shank b to pass downward within it.

The bottom part of the footA is provided with four bosses a These fourbosses lay at the angles of a square, and between them is a part of thebase, cruciform in shape, and each branch a of the cross is sufficientlywide to permit the cross-bar 5 to rest upon it,

with two of the bosses on either side of the cross-bar b The distancebetween the bottom of the foot-piece A and the under side of the returnpart a, is equal to or slighly less than the perpendicular thickness ofthe crossbar b In order to fasten the parts securely together the bottompart is placed with its crossbar 17 between the uprising ends of thefoot part A and forced downwarduntil the upper side of the cross-bar bhas passed below the lower surface of theparts a. The bottom is thengiven a quarter-turn and the cross-bar b ,'rising over the boss a takesa positlon 1n the arm a of the cross, between the bosses. In making thequarter-turn the parts a have been sprung slightly upward; but as soonas the quarter turn is completed they return downward and hold thecross-bar b securely in place between the bosses and prevent the buttonfrom again turning until conslderable force has been used to producethat result.

In use the uprising parts of the foot-piece pass through the buttonholeof the fabric and prevent any frictional contact between the buttonholeand the stem b.

The face of the button may be finished in any way. I

In a button formed in this'way there are no small springs to be securedin place and to be easily got out of repair. The bosses a can be made onthe under side of the upper part a, if it is desired, and be equallyefficient.

What'I claim as novel is- In a separable button, the combination of ahead part provided with a shank and crossbar and a foot-piece made ofone piece of metal, having the two ends bent inward and upward, so as toform from the same piece of metal the upper and under parts of thefootpiece, and a spring connection between the two, said lower portionof said footpiece being formed with a holding-seat lying across theopening between the upturned ends, substantially as and for the purposedescribed.

In testimony whereof I sign this specification in the presence of twowitnesses.-
